They've said before that the reuseables are not a mechanic they intend to repeat, so it seems unlikely there will be a lot of BoP purple consumeables at the new tiers. You may want to pick up a biochem alt to make stuff for yourself, but it doesn't seem like there will be any skill you need to have just to be able to use particular must-have kit at the endgame anymore.

They may have said that, but it appears they lied, as there are currently purple reusable of the current top stim/, med-pack/adrenal available on PTS
